The next generation Kia Optima, known as the Magentis in some markets, will make its world debut at the New York Auto Show, which opens on 2nd April.

Based on the design sketch, we can see that Kia has ditched the distinctly three-box, uninspiring looks of the current car for a sleeker and sexier design. Of course, the actual car will be toned down from this, but we expect a looker based on Kia’s recent track record. The Korean brand promises “bold, athletic and sporty visual energy” for its D-segment challenger.

Little else is known for now, but Kia has revealed that the new Optima is longer, lower and wider than the car it replaces, and features a “significantly longer wheelbase”. For reference, the current car measures 4,800 mm long, 1,805 mm wide and 1,480 mm tall, with a 2,720 mm wheelbase.

The Optima will go on sale in the USA late this year, while European sales will start in spring 2011. More images after the jump!
